Unique technology of three elements to give thermal spray a superimposed effect

       Thermal spray technology started at the beginning of the last century, invented by Swiss M.U. Schoop in 1913. At first, only the molten metal was formed into a liquid stream with compressed air, which was sprayed onto the surface of the coated substrate to form a film-like structure. The spraying temperature, the impact velocity of the droplet on the surface of the substrate and the properties of the material forming the coating constitute the core of spraying technology. The entire development of thermal spraying technology is basically advancing along these three main lines. Temperature and speed depend on different heat sources and equipment configurations. In a sense, the higher the temperature and the faster the speed, the more conducive to the formation of excellent coatings, which leads to the competition and coordination of the two elements of temperature and speed in the entire technological development process. The selectivity of various spraying materials is another advantage of the thermal spraying index, which can make the working surfaces of different equipment "point iron into gold, wear helmets and armor". It is these three elements that make thermal spraying a unique technology with a truly additive effect, enabling the design of surfaces with the wide variety of properties required, from general mechanical maintenance to high-tech fields such as aerospace and bioengineering.
